NON-VOLATILE MEMORY CELL ARRAY AND NON-VOLATILE MEMORY DEVICE

摘要

PURPOSE: A nonvolatile memory cell array and a nonvolatile memory device are provided to improve performance by shortening an erase operation time. CONSTITUTION: A nonvolatile memory cell array(10) includes a page and an erase marker. The page comprises one or more nonvolatile memory cells. The erase marker corresponds to the page and displays whether the page is erased or not. The nonvolatile memory cell is a nonvolatile memory cell which performs an over-write function and includes a phase-change random access memory. An erase marker comprises a phase change memory cell.
